What was your reason for replacement in the first place?
Have you got power at relay?

-Ign "Off"
-Disconnect Fuel Pump Relay
-Probe CKT 340 (the Orange Wire ) with a Test Light to Ground
Result: should have 12 volts

Connect Test Light between CKTS 340 (Orange wire) and 450 (Black w/white ground)
Result: should have 12 volts

Connect Test Light between Harness CKT 465 (Green w/white wire) and Ground
-Ign "ON" for 10 seconds
Should light for 2 second showing ECM is sending signal to relay

What was the original problem? No fuel pressure? Did you check the fuse?

Nope. I was cruising around in the old posts and added something to some of them. I totally forgot it would bring them back from the dead. Sorry guys. I screwed up so please let it go.
